obspy.signal.array_analysis.array_transff_freqslowness¶

array_transff_freqslowness(coords, slim, sstep, fmin, fmax, fstep, coordsys='lonlat')[source]¶

Returns array transfer function as a function of slowness difference and frequency.

Parameters:

coords (numpy.ndarray) coordinates of stations in longitude and latitude in degrees elevation in km, or x, y, z in km
coordsys (str) valid values: ‘lonlat’ and ‘xy’, choose which coordinates to use
slim either a float to use symmetric limits for slowness differences or the tupel (sxmin, sxmax, symin, symax)
fmin (float) minimum frequency in signal
fmin maximum frequency in signal
fmin frequency sample distance
